MACHINE non SERVING TACKS, nAILsnTd ,7 Application filedi February This invention relates particularly to a machine adapted to the purpose of receiving tacks, nails, or the like,'an d serving them out for use, as required. 1 i

Such a machine may 'be usefully employed,

for example, in factories engaged inthe manufacture of upholstered furniture. In such factories, it is necessary to employ tacks of different sizes, or kinds; and where the tacks are taken from kegs, there is great danger that workmen'will throw tacks originally taken from ,o'ne'keg into another keg,and thus destroy the proper assortment.

In accordancewith the presentinvention,

'" a plurality of receptacles are provided, each of which is of suitable size to receive an entire keg of nails. These receptacles may be kept locked, so that there is no possibility of the workmen returning tacks to them and making errors which might result in spoiling the assortment. The receptacles are provided with means for serving or dispensing the tacks to the workmen, as they are required.

The invention is illustrated in its preferred embodiment in the accompanying drawings,

in which Fig. 1 shows a front elevational view of a machine provided with four independently sectional view of one of the receptacles, taken as indicated at line 3 of Fig. 1; Fig. 4 is a broken longitudinal vertical sectional view taken as indicated at line 4 of Fig. 2; Fig. 5

is a plan view of the machine with two of the p receptacles removed; Fig. 6 is a vertical sectional view through one of the hoppers, one of these hoppers being disposedpbeneath each receptacle, the section shown in Fig. 6 being taken as indicated at line 6 of Fig. 5; and Fig. 7 is a detailed sectional view through the discharge spout of one of the hoppers, the section being taken as indicated at line 7 of Fig. 1.

In the illustration given, A represents a frame; B represents a series of receptacles journalled in the upper portion of said frame; andC represents a series of stationary hoppers mounted on the frame beneath the receptacles.

The frame A may struction. In the illustration given, it is shown of rectangular form and constructed principally of angle iron. The upper portion of the frame supports a trunnion 1 which side-walls near their centers-with diametribe of any suitable con -s 12, 1925 serial 1%. $7 24.

extends r e-[T v I The receptacles B are provided in their cally opposite openings equipped with rein forcement rings, or bearings, 3.. The shaft 1' between the end-standards 2' of the extends-through these bearings, and the re ceptacles' are thus independently journall e'd on the trunnion 1. Each receptacle preferably is in the form of'acylindrical vessel of sheet-metal, and is equipped with a removable lid 4. The lid is removable, but is secured in position by means ofa bar 5 which extends diametricallyacross the lid and through perforateears 6 which"p r'0ject upwardly from the vessel. One end ofthe bar 5'is provided with a lug 5 and the other end is provided with a. perforation which receives a padlock 5" I Each vessel B is provided at its front side, near its upper end, with a discharge opening 7 which opensinto a discharge-chute 8which is secured to the front Wall of the Vessel. In the discharge chamber 8 is mounteda valve, 9 which is secured to arshaft 10 which projects through the'lateral walls of the chamber 8. One end of the shaft 10 is equipped with an actuating lever 11 which is connected by a spring 12 with the body of the vessel B. The spring serves to hold the valve 9 normally in a position .to close the passage through the chamber 8. The lower end of the chamber 8 is provided with afunnel-shaped V discharge portion 8. The lid of the vessel B is equipped with a handle13.

gThe hoppers C have their upper ends secured to longitudinal bars 14 constituting part of the frame A; These hoppers are open at their upper ends,.and project some distance in front of the vessels B. The hoppers have forwardly and downwardly inclined bottoms 15, and are equipped at their lower front portions with discharge funnels 15 Slidevalves 16mounted in suitable guides and equipped at their front endsiwith handles 1 6 serve normally to close the upper endsgof the funnels 8". "Springs 17 hold the slide 7 valves 16 normally in the closed position.

In the use of the machine, a keg of tacks,

for example, is opened and dumped into each receptacle B. The receptacle is then closed and locked. The receptacles B may be suit I ably numbered to indicate the sizes of the tacks inthe various receptacles. When a "workman desires a'supply of tacks, he tilts,

or rotates, the receptacle B forwardly, thus causing a supply of tacks to be discharged into the upper portion of the front, or'auxiliary, chamber 8. He allows the vessel to return to its normalposition, and then places a can, or cup, beneath the spout 8. He then depresses the lever 11, thus throwing the valve 9 downwardly and permitting the tacks to be discharged into the can, or container, which he employs-to receive them. Suitable spaceis provided above the hoppers C to enable the small container which the workmen carry to be placed in position beneath the spout 8. Any overflow of. tacks will be caught by the hopper C; and when there is a sufficient accumulation, the slide valve 16 may be opened and the tacks may be caught by a container placed beneath the dischargefunnel 15.

A device of the character described can be manufactured at moderate cost, and affords an exceedingly handy and useful device for the purpose set forth. 7

Itmaybe added that the center of gravity of the vessel B is somewhat below the trunnion 1, so that the vessel normally will sume an upright position. The vessel may be rotated in a forward direction to a completely inverted position, if necessary, to enable the contents to be discharged through the opening 7.

The foregoing detailed description has been given for clearness of understanding only, and no unnecessary limitations should be understood therefrom, but the appended claim should be construed as broadly as permissible, in View of the prior art.

What I regard as new, and desire to secure by Letters Patent, is:

In a machine of the character set forth, the combination of a frame, a series of-st'ationary hoppers mounted in the lower portion of said frame, a trunnion extending horizontally over said hoppers, and a series of ves sels having their side walls provided with perforations through which said trunnion extends, said vessels being equipped at their front sides with discharge chutes, having ports at their upper ends communicating with the upper portions of said vessels.
